Description

{WRIST WEARABLE BLOOD PRESSURE MONITOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood pressure monitor for measuring blood pressure, and more particularly, to a portable wrist blood pressure monitor which can easily measure a blood pressure by simple operation while being worn / carried on a wrist like a wristwatch.

Generally, the blood pressure is measured as the blood pressure on the wall of the blood vessel, and the heart repeats shrinkage and relaxation about 60 to 80 times per minute. When the heart contracts and pushes out the blood, the pressure on the blood vessel is called 'contracting blood pressure' and is called 'hypertension' because it is the highest. In addition, when the heart relaxes and receives blood, the pressure of the blood pressure is called 'relaxed blood pressure' and the lowest is called 'the lowest blood pressure'.

The normal blood pressure of a normal person is 120 mmHg in shrinking blood pressure and 80 mmHg in relaxed blood pressure. More than 1 out of 4 adults in Korea are hypertensive, and this ratio is increasing rapidly after age 40, and some patients are classified as hypotension.

The problem of hypertension is that it may cause other complications that may pose a life threatening condition such as eye disease, kidney disease, arterial disease, brain disease, heart disease if left without proper management of hypertension. Therefore, in the case of the above-mentioned complication or the complication, continuous measurement and management of the blood pressure should be performed.

BACKGROUND ART [0002] Various kinds of blood pressure measuring devices have been developed as interest in health related diseases and geriatric diseases such as hypertension has increased.

The blood pressure measurement method includes a Korotkoff sounds method, an oscillometric method, and a tonometric method.

The stethoscope method is a typical pressure measurement method. In the process of decompressing the blood flow by applying sufficient pressure to the body part passing through the arterial blood, the pressure at the moment when the pulse sound is heard for the first time is measured by systolic pressure And the pressure at the moment when the pulsation disappears is measured by diastolic pressure.

The oscillometric method and the tonometric method are applied to a digitized blood pressure measuring device.

The oscillometric method is a method in which the body part through which the arterial blood passes is decompressed at a constant speed so as to block the arterial blood flow as in the stethoscopic method or a pulse wave generated during the pressure step- And measures systolic blood pressure and diastolic blood pressure.

Here, the pressure at the time when the amplitude of the pulse wave is maximum can be measured by the systolic blood pressure or the diastolic blood pressure, and the pressure when the rate of change of the pulse wave amplitude is rapidly changed is measured by the systolic blood pressure or the diastolic blood pressure You may.

In the process of reducing pressure at a constant rate after pressurization, the systolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum, and the diastolic blood pressure is measured later than the moment when the amplitude of the pulse wave is maximum. On the contrary, in the process of increasing the blood pressure at a constant speed, the systolic blood pressure is measured later than the moment when the amplitude of the pulse wave is the maximum, and the diastolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum.

Next, in the tonometric method, a constant pressure of a magnitude not blocking the blood flow of the artery is applied to the body part, and the blood pressure can be continuously measured using the size and shape of the pulse wave generated at this time.

As described above, the blood pressure monitor for measuring the blood pressure is the most basic medical equipment for measuring the blood pressure which is the basis of the health index. It is almost indispensable not only in general medical clinics but also for home blood pressure measurement It is in use.

However, in the case of a conventional blood pressure monitor, when the blood pressure is mostly measured, the blood pressure is measured by winding the blood pressure meter on the upper arm (upper arm or upper arm, part from the shoulder to the elbow) It is not easy to easily measure the blood pressure when desired.

For example, in the conventional oscillometric blood pressure monitor, a blood pressure monitor body and a pressure cuff, a tube plug, an air hose, and the like are required for wrapping around the forearm. It is bulky and has a disadvantage in that it is cumbersome to use because there is a lot of preparations in the preparation of the measurement, for example, the air hose must be fitted downward for proper measurement at the time of use or the cuff should be worn 1 to 2 cm above the elbow.

Particularly, since blood pressure varies depending on the body characteristics of the subject, patients having complications in the body need to immediately measure the blood pressure every time the subject feels abnormality in the body and / or the body. The mercury sphygmomanometer and the electronic blood pressure monitor Thereby providing inconvenience to the patients due to the following problems.

First, the mercury sphygmomanometer and the electronic sphygmomanometer use a cuff requiring air injection. However, the cuff has a bulky size, so that it is troublesome for a user to wear it in real time.

In addition, since the mercury sphygmomanometer using the pneumatic cuff is often excessively bulky and heavy for a patient whose blood pressure is frequently measured, it is inconvenient and inconvenient for the subject (patient) to carry around, and each time the blood pressure is measured, It is troublesome to detach and attach the blood pressure monitor.

Although there is a pneumatic electronic blood pressure monitor having the same accuracy as the conventional blood pressure monitor described above, when the blood pressure is measured periodically while the patient continues to carry it, since the electric pump and the infusion cuff are used, There is a problem that the behavior of the patient becomes uncomfortable.

In addition, there are non-pressure type electronic blood pressure monitors that measure blood pressure based on the pulse of the wrist or the fingertip and various parameters. However, since it is difficult to accurately specify the parameters and provide general purpose, the blood pressure is measured periodically It is difficult to apply to patients with

Meanwhile, in recent years, a blood pressure monitor capable of measuring blood pressure while being worn on a wrist, such as a wristwatch, has been developed in the name of a wrist blood pressure monitor, a wrist blood pressure monitor or a wristwatch blood pressure monitor.

However, the conventional wrist blood pressure monitor simply measures the blood pressure by wearing it on the wrist, so it is called a wristwatch type, but it is practically not so small as to be worn on a wrist. In other words, a conventional wrist blood pressure monitor can be said to be only slightly reduced in size so that it can be applied to the wrist instead of the upper wrist, and other wrist blood pressure monitors are structurally complicated, equipped with a mechanical / electronic pumping device for wrist pressurization, There is a problem such that the failure occurs easily and the manufacturing cost increases.

Korean Patent Publication No. 10-2009-0046279 (Published Date; May 11, 2009) Korean Patent Publication No. 10-2002-0061226 (published date: July 24, 2002) Japanese Utility Model Utility Model Publication No. 6-11701 (published date: February 15, 1994)

The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a wrist blood pressure monitor that can easily measure blood pressure by simple operation of the opposite hand while wearing it on the wrist of one arm, It has its purpose.

For example, the distance from the middle of the pumping chamber to the middle of the airbag is 1/4 to 1/2 of the circumferential length of the wrist blood pressure monitor. Therefore, if a blood pressure check is required while the user wears the wrist blood pressure monitor on the wrist of one arm while carrying the wrist blood pressure monitor while carrying the wrist blood pressure monitor, the user presses the pumping chamber with the finger of the other hand to fill the airbag, The blood pressure can be checked by pressing the airbag by the palm of the hand so that blood pressure can be easily measured by a simple operation.

And, when the wrist blood pressure gauge is worn on the wrist, at least a part of the airbag is positioned inside the wrist so as to cover the region where the radial artery passes, so that at least a part of the pumping chamber is disposed inside the wrist The pumping chamber may be provided in the airbag in the direction of the bone (ulna). For example, the distance from the middle of the pumping chamber to the middle of the airbag is 1/8 to 3/8 of the circumference of the wrist blood pressure monitor. In this case, if a blood pressure check is needed while the user wears the wrist blood pressure monitor on the wrist of one arm while carrying the wrist blood pressure monitor while carrying the wrist blood pressure monitor, when the user presses the pumping chamber with the palm of the other hand to fill the airbag and rolls the palm holding the pumping chamber, Since the airbag is pressed by another portion (relatively upper portion) of the same palm, blood pressure can be checked, and blood pressure can be easily measured by a simple operation.

The airbag and the pumping chamber being connected by a first check valve; A second check valve is connected to one side of the pumping chamber to supply the outside air to the pumping chamber; An exhaust valve for reducing the pressure of the airbag is connected to one side of the airbag.

According to the present invention, since the blood pressure monitor can be conveniently worn like a wristwatch at any time, the blood pressure can be conveniently measured whenever necessary, and the pumping chamber for filling the air bag is restored to its original shape by its own elasticity, It is possible to simplify the structure, simplify the construction, reduce the manufacturing cost, and reduce the burden on the battery capacity since no separate energy source is consumed for filling the air. have.

According to the present invention, it is possible to easily increase the air pressure inside the airbag. When the operation of the pump for filling the airbag and the pressing of the wrist are narrower in the range of the size of one hand, The operation of the blood pressure monitor is easy and accurate measurement is possible.

Further, according to the present invention, it is possible to provide a simple blood pressure measurement device that does not interfere with the behavior of the subject who has to periodically measure the blood pressure, thereby providing the user with convenience in measuring the blood pressure.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing embodiments of the present invention, the same reference numerals are used for the same configurations.

First, an embodiment (first embodiment) of the present invention will be described with reference to Figs. 1 to 4. Fig. 1 is a cross-sectional view showing an embodiment of a wrist blood pressure monitor according to the present invention, and Figs. 2 (a) and 2 (b) show a state where the wrist blood pressure monitor shown in Fig. 1 is worn on a user's left wrist FIG. 3 is a developed view schematically showing the internal configuration of the wrist blood pressure monitor shown in FIG. 1, and FIG. 4 is a plan view showing a display unit of the wrist blood pressure monitor shown in FIG.

1 and 4, the wrist blood pressure monitor 100 according to the present embodiment is a portable blood pressure monitor that can be worn on the wrist of a subject (user) at all times, that is, a wrist strap that is worn on the wrist. And a display unit 120 for displaying the blood pressure of the wearer.

In the present embodiment, the wrist strap 110 is in the form of a strap that wraps the wrist. The display unit 120 is attached to the wrist strap 110 and is attached to the user's wrist by the wrist strap 110.

More specifically, the wrist strap 110 includes a base strap 111, an air bag 112, and a pumping chamber 113. The base strap 111 is a ground structure of the wrist strap 110, and the display strap 111 is mounted on the base strap 111.

In the present embodiment, the wrist blood pressure monitor 100 is a ring type of a closed loop structure continuously connected to a specific position without a separate fastening portion. For example, the wrist strap 110 may be constructed as an integral band structure that can be resiliently widened, that is, an elastic wristband that can be extended widely by an external force. Of course, a wrist strap is also possible, which has a structure in which the wrist strap is detachable, that is, a structure that can be divided, as in the embodiment (third embodiment) described later, and can be tightened according to the thickness of the wrist of the subject.

The airbag 112 is provided on the base strap 111 so as to press the user's wrist, and a fluid space, for example, air, is formed in the airbag 112.

Next, the pumping chamber 113 is used to fill the air bag 112 with the air bag 112, and is connected to the air bag 112 in the base strap 111 . In the present embodiment, the pumping chamber 113 is contracted by an external pressure to supply air to the airbag 112, and inflates by self-elasticity to suck outside air.

In other words, when the user presses the pumping chamber 113, the air in the pumping chamber 113 is supplied to the air bag 112. When the external pressure that presses the pumping chamber 113 is removed, Is inflated into its original shape by its own elasticity, and sucks the outside air.

Accordingly, as the pumping chamber 113 is restored to its original shape, external air is naturally introduced into the pumping chamber 113. To this end, the pumping chamber 113 has an elastic material such as a rubber material, and it may be a structure or material that is restored to its original shape by elasticity when an external pressure, that is, a force pressing the pumping chamber 113 from the outside, is removed .

Air flow between the airbag 112 and the pumping chamber 113 is made only in one direction, i.e., from the pumping chamber 113 to the airbag 112 direction. In other words, a valve 114, that is, a check valve, which passes the fluid (air) flowing from the pumping chamber 113 only to the air bag 112 and blocks the flow in the opposite direction, And the pumping chamber 113. The airbag 112 and the pumping chamber 113 are connected by the check valve 114. The check valve 114 is connected to the airbag 112 and the pumping chamber 113,

The first check valve 114 is provided in the flow path 115 for communicating the airbag 112 and the pumping chamber 113 so that the airbag 112 is pumped from the pumping chamber 113. [ Thereby preventing the air introduced into the pumping chamber 113 from flowing back to the pumping chamber 113 again.

A second check valve 116 for supplying external air to the pumping chamber 113 is connected to one side of the pumping chamber 113. The second check valve 116 is provided at a suction port of the pumping chamber 113 and blocks the air flowing into the pumping chamber 113 from the outside of the pumping chamber 113, that is, outside air through the suction port .

An exhaust valve 117 for reducing the pressure of the airbag 112 is connected to one side of the airbag 112. The exhaust valve 117 gradually discharges air when the airbag 112 is pressed by the user to realize the gradual depressurization of the airbag 112. The exhaust valve 117 is provided at an exhaust port of the airbag 112. An example of the exhaust valve 117 may be a linear valve having constant air discharge over time.

The display unit 120 is provided with a circuit board 130 and a pressure sensor 140 is connected to the circuit board 130. The pressure sensor 140 senses the pressure of the airbag 112 and transmits a pressure signal to the circuit board 130. The pressure sensor 140 is installed on one side of the airbag 112 and connected to the circuit board by a signal line 131. The circuit board 130 is connected to the inside of the display unit 120 And is arranged on the opposite side of the pumping chamber 113 with respect to the airbag 112. However, the arrangement structure of the pressure sensor and the circuit board 130 is not limited.

Referring to FIG. 4, the display unit 120 has a blood pressure display window 121 for displaying blood pressure.
